第 4 週：一顆有使命的罌粟籽
你的寶寶現在大約有...大小 一顆罌粟籽.
平均長度: 0.2 厘米
(頭臀長)
本週寶寶發育
您的寶寶現在已經是一個胚胎了，像一顆罌粟籽（Poppy seed）那麼大，並已經在您的子宮裏「安家落戶」啦！一個充滿液體的羊膜囊正在形成，為它提供溫柔的保護。胎盤也開始馬不停蹄地建設，很快就會為寶寶輸送氧氣和養分。
本週你的身體變化
您可能會感到類似經前綜合症（PMS）的脹氣或乳房脹痛，有些準媽媽還會出現少量的「着床出血」。不過，完全沒感覺也是正常的！雖然有些驗孕棒聲稱可以提早檢測，但建議等到月經遲來的第一天再測，結果會最準確哦。
給伴侶的貼士
如果測出了兩道槓，快與太太一起慶祝喜訊吧！她的身體正在為了孕育生命而加班加點，可能會感到非常疲憊。主動分擔一些家務就是對她最好的支持。您的愛是她最堅強的後盾。
